The molding process of the bamboo tongue depressor is mainly to first make the bamboo into bamboo strips, and then cut the bamboo strips into blanks of fixed length, and then edge mold and polish the blanks to form a smooth surface.

[0003] At present, bamboo tongue depressor blanks need to be cut into fixed lengths before entering a molding machine for cutting and grinding, and are generally transported by a conveyor belt. However, bamboo and wood, which are raw materials, are different from plastics and have uneven textures. Their surfaces are prone to cracks, breakages, wormholes and other defects after cutting. In addition, a small number of individuals that do not meet the standards will appear in the blanks after cutting, and they need to be screened out before being sent to the molding machine. Therefore, an automatic feeding, sorting and conveying device for tongue depressors is proposed. Summary of the invention

Figure 4 As shown, an upper inclined platform 6 is fixedly installed on the top of the inspection platform 5. The upper inclined platform 6 is arranged on the side of the upper conveyor belt 4 away from the lower hopper 2 and is adapted to the upper conveyor belt 4. Figure 5 As shown, a flap panel 7 is provided on the side of the upper ramp 6 facing away from the upper conveyor belt 4, and the upper ramp 6 is located between the upper conveyor belt 4 and the flap panel 7. Figure 7 As shown, a turning shaft 8 is fixedly installed at the bottom of the turning panel 7, and the turning shaft 8 is rotatably installed on the top of the inspection table 5. In this embodiment, as shown in FIG. Figure 4 As shown, the two ends of the flip shaft 8 are rotatably sleeved with two brackets, and the flip shaft 8 is rotatably suspended on the top of the inspection table 5 through the brackets, as shown in FIG. Figure 7 As shown, a receiving groove 601 is provided inside the upper inclined platform 6. Figure 4 As shown, a horizontally arranged electric push rod 9 is fixedly installed on the top of the inspection table 5. Figure 5 As shown, a pusher frame 10 is fixedly mounted on the telescopic end of the pusher electric push rod 9. Figure 7 As shown, one end of the pusher frame 10 extends to the interior of the receiving groove 601 and is fixedly mounted with a pusher plate 11. Figure 5 As shown, a lower inclined platform 17 is provided on the side of the flip panel 7 away from the upper inclined platform 6, and the lower inclined platform 17 is fixedly installed on the top of the inspection platform 5, as shown in FIG. Figure 2 As shown, a lower conveyor belt 18 is provided on the side of the lower inclined platform 17 away from the flip panel 7. In this embodiment, the heights of the inspection platform 5, the upper inclined platform 6, the flip panel 7, the lower inclined platform 17 and the lower conveyor belt 18 are gradually reduced in a step-like manner, and an inspection component is provided on the top of the flip panel 7;

[0038] The inspection component is used to inspect the forming quality of the blank transferred to the flap 7, such as Figure 5As shown, the inspection assembly includes two waste push plates 12 arranged on the top of the flip panel 7, the flip panel 7 is located between the two waste push plates 12, the top of the two waste push plates 12 is fixedly installed with the same suspension frame 13, the top of the suspension frame 13 is fixedly installed with a visual scanner 14, the visual scanner 14 faces the flip panel 7, and the top of the inspection table 5 is fixedly installed with a flip motor 15. Figure 7 As shown, the output shaft of the flip motor 15 and one end of the flip shaft 8 are fixedly sleeved with a flip gear 16, and the two flip gears 16 are meshed with each other; specifically, when the tongue depressor automatic feeding sorting and conveying device is in use, the cut blanks are first poured into the lower hopper 2 in batches, and the oscillators 3 on both sides of the lower hopper 2 are started to make the lower hopper 2 oscillate continuously, so that the blanks inside the lower hopper 2 fall from the bottom end of the lower hopper 2 onto the upper conveyor belt 4 one after another, so that the upper conveyor belt 4 transports the blanks until the blanks slide along the upper inclined platform 6 at one end of the upper conveyor belt 4 onto the flip panel 7 for inspection. By setting an inspection component, when the blanks fall on the flip panel 7, the visual scanner 14 on the top of the suspension frame 13 will visually scan the blanks to check the length, width and surface quality of the blanks. After the inspection is completed, the flip motor 15 is turned on. The machine 15 will drive the flip shaft 8 to rotate through the meshing flip gear 16, and then drive the flip panel 7 to flip toward the upper inclined platform 6, until the blank is turned over and falls on the upper inclined platform 6 again. At this time, the flip panel 7 is reset, and the blank slides along the upper inclined platform 6 and falls on the flip panel 7 again, so that the visual scanner 14 can check the other side of the blank, and realize automatic detection of both sides of the blank to prevent unqualified blanks from continuing to be transported, affecting the actual yield rate. When the specifications of the blank meet the requirements and there are no defects on the surface, the pushing electric push rod 9 drives the pushing plate 11 to slide out of the accommodating groove 601 through the pushing frame 10, and abuts against the side of the blank, pushing the blank to move to the lower inclined platform 17 on one side of the flip panel 7, and slides onto the lower conveyor belt 18 for transportation again, so as to carry out the subsequent grinding and molding process.

[0039] like Figure 4 As shown, a dust collecting device 19 is provided on one side of the inspection table 5. Figure 5 As shown, a dust collecting fan 20 is fixedly installed on the top of the dust collecting device 19, and the dust collecting fan 20 is connected to the air inlet end of the dust collecting device 19. A clearance hole is opened on the top of the inspection table 5, and the top end of the dust collecting fan 20 passes through the clearance hole and extends to the bottom of the flip panel 7. Figure 6As shown, a plurality of chip removal holes 701 are provided on the top of the flap panel 7; specifically, by arranging the dust suction device 19, when the blank is transported, the dust suction device 19 will be started in advance, so that a negative pressure is formed inside the dust suction blower 20, and the surface of the flap panel 7 is dusted through the chip removal holes 701, so that the wood chips on the surface of the flap panel 7 and both sides of the blank are directly sucked into the dust collecting bag inside the dust suction device 19, thereby greatly reducing the accumulation of wood chips on the flap panel 7, reducing the interference of wood chip adhesion on the scanning of the visual scanner 14, and reducing the burden on the subsequent grinding and molding process.

[0040] like Figure 6 As shown, a plurality of chip holes 701 are evenly arranged on the top of the flip panel 7; specifically, by setting the chip holes 701, a large number of chip holes 701 on the flip panel 7 can be arranged according to a specified scale, and the evenly arranged chip holes 701 can serve as an identifier or reference. When the blank falls on the flip panel 7, the chip holes 701 can provide an auxiliary reference function for the visual scanner 14, so that the visual scanner 14 can more accurately identify the specifications of the blank.

[0041] like Figure 4 As shown, a sunshade 21 is fixedly installed on the top of the suspension frame 13; specifically, by setting the sunshade 21, the sunshade 21 can block a large range of ambient light, thereby preventing the ambient light from directly hitting the lens of the visual scanner 14 and causing interference to the visual scanner 14.

[0042] like Figure 4 As shown, a support frame 22 is fixedly installed on one side of the top of the inspection table 5, and a horizontally arranged waste electric push rod 23 is fixedly installed on the top of the support frame 22, and the telescopic end of the waste electric push rod 23 is fixedly installed on the side wall of the waste push plate 12 on one side; specifically, by setting the waste electric push rod 23, when the visual scanner 14 recognizes that the specifications of the current blank do not meet the requirements, or there are defects on the surface of the blank, the waste electric push rod 23 will start and push the waste push plate 12 on one side, and then drive the two waste push plates 12 to move synchronously through the suspension frame 13, and bring the blank on the flip panel 7 away from the top of the flip panel 7, so as to realize the automatic removal of blank waste and prevent the waste from flowing into the subsequent process flow.

[0043] like Figure 2 As shown, two electric conveying slide rails 24 are arranged on the side of the inspection table 5 away from the waste electric push rod 23, and the electric conveying slide rails 24 are arranged horizontally. Figure 8 As shown, the top of the transmission electric slide rail 24 is driven and installed with an electric slide 25, as shown in FIG. Fig. 9As shown, the tops of the two electric slides 25 are fixedly mounted with the same lower fixed plate 26, and the top of the lower fixed plate 26 is rotatably mounted with an upper rotating plate 27. In this embodiment, one of the sides of the lower fixed plate 26 and the upper rotating plate 27 is hinged to each other, and a flip handle 30 is located on the side of the waste box 29 away from the hinge of the lower fixed plate 26 and the upper rotating plate 27. A weighing platform 28 is fixedly mounted on the top of the upper rotating plate 27, and a waste box 29 is fixedly mounted on the top of the weighing platform 28. A flip handle 30 is fixedly mounted on one side of the waste box 29, as shown in FIG. Figure 2 As shown, a discharge ramp 31 is fixedly installed on the top of the inspection table 5, and the discharge ramp 31 is located between the flip panel 7 and the waste box 29; specifically, by setting the waste box 29, unqualified blanks will be pushed away from the top of the flip panel 7, so that the waste will fall into the waste box 29 along the discharge ramp 31 for collection, and when the weighing platform 28 senses that the overall weight of the waste box 29 exceeds a predetermined threshold, the two transmission electric slides 24 will drive the two electric slides 25 to carry the waste box 29 to one end. At this time, the staff can pull the flip handle 30 on the back side of the waste box 29 to drive the waste box 29 to rotate along the hinge center of the upper rotating plate 27 and the lower fixed plate 26, and dump the waste inside the waste box 29, thereby realizing automatic collection and semi-automatic transportation of waste.

[0044] like Figure 2 As shown, the two electric slides 25 are fixedly sleeved with the same dust cover 32, which is located at the top of the transmission electric slide rail 24 and the bottom of the lower fixed plate 26; specifically, by setting the dust cover 32, when the waste is pushed down the flip panel 7, a small amount of wood chips remaining on the waste will fall off, and the dust cover 32 can prevent a small amount of fallen wood chips from being blown by the ambient airflow and deviating from the falling trajectory and directly scattering on the transmission electric slide rail 24, affecting the coordinated driving of the transmission electric slide rail 24 and the electric slide 25.

[0045] like Figure 3 As shown, a hanging frame 33 is fixedly installed inside the unloading rack 1, and a cylindrical outer shell 34 and a sorting motor 35 are fixedly installed on the hanging frame 33. The cylindrical outer shell 34 is located at the bottom of the unloading hopper 2, as shown in FIG. Fig.10As shown, a sorting core column 36 is rotatably installed inside the cylindrical outer shell 34, and the output shaft of the sorting motor 35 is drivingly connected to the sorting core column 36. A plurality of evenly distributed sorting partitions 37 are fixedly installed on the circumference of the sorting core column 36. Through holes 3401 are provided on the top and bottom of the cylindrical outer shell 34, and the position of the through holes 3401 is consistent with the position of the bottom end of the lower hopper 2; specifically, by setting the sorting partitions 37, the blanks falling from the bottom end of the lower hopper 2 will successively pass through the through holes 3401 at the top and fall between the two sorting partitions 37, and then the sorting motor 35 drives the sorting core column 36 to rotate, so that the two sorting partitions 37 with the blanks are gradually turned to the bottom, and the subsequent falling blanks will fall again between the next group of two sorting partitions 37, so that many blanks are successively stuck on the circumference of the sorting core column 36 and fall on the upper conveyor belt 4 through the through holes 3401 at the bottom, thereby realizing automatic sorting and falling of the blanks, and greatly reducing the disorder of blank discharge.

[0046] In summary: when the automatic feeding and sorting and conveying device for tongue depressors is in use, the cut blanks are first poured into the lower hopper 2 in batches, and the oscillators 3 on both sides of the lower hopper 2 are started to make the lower hopper 2 vibrate continuously, so that the blanks inside the lower hopper 2 fall from the bottom end of the lower hopper 2 onto the upper conveyor belt 4 one after another, so that the upper conveyor belt 4 transports the blanks until the blanks slide along the upper inclined platform 6 at one end of the upper conveyor belt 4 and fall onto the flip panel 7 for inspection. By setting up an inspection component, when the blanks fall on the flip panel 7, the visual scanner 14 on the top of the suspension frame 13 will visually scan the blanks to check the length, width and surface quality of the blanks. After the inspection is completed, the flip motor 15 will drive the flip shaft 8 to rotate through the meshing flip gear 16, thereby driving the flip panel 7 to move upward. The inclined table 6 flips over until it drives the blank to turn over and fall on the upper inclined table 6 again. At this time, the flip panel 7 is reset, and the blank slides along the upper inclined table 6 and falls on the flip panel 7 again, so that the visual scanner 14 can check the other side of the blank, thereby realizing automatic detection of both sides of the blank, so as to prevent unqualified blanks from continuing to be transported and affecting the actual yield rate. When the specifications of the blank meet the requirements and there are no defects on the surface, the pushing electric push rod 9 drives the pushing plate 11 to slide out of the accommodating groove 601 through the pushing frame 10, and abuts against the side of the blank, pushing the blank to move to the lower inclined table 17 on one side of the flip panel 7, and slides on the lower conveyor belt 18 for transportation again, so as to carry out the subsequent grinding and molding process. By arranging the dust suction device 19, the dust suction device 19 can be used when the blank is transported. The device 19 will be started in advance to form a negative pressure inside the dust suction blower 20, and the surface of the flip panel 7 will be dusted through the chip dropping holes 701, so that the wood chips on the surface of the flip panel 7 and both sides of the blank are directly sucked into the dust collecting bag inside the dust suction device 19, which greatly reduces the accumulation of wood chips on the flip panel 7, reduces the interference of wood chips adhesion to the scanning of the visual scanner 14, and reduces the burden on the subsequent grinding and molding process. By setting the chip dropping holes 701, the numerous chip dropping holes 701 on the flip panel 7 can be arranged according to the specified scale, and the evenly arranged chip dropping holes 701 can serve as a mark and reference. When the blank falls on the flip panel 7, the chip dropping holes 701 can provide the visual scanner 14 with an auxiliary reference function, so that the visual scanner 14 can adjust the size of the blank. The identification of the grid is more accurate. By setting the sunshade 21, the sunshade 21 can block a large range of ambient light to prevent the ambient light from directly hitting the lens of the visual scanner 14 and causing interference to the visual scanner 14. By setting the waste electric push rod 23, when the visual scanner 14 recognizes that the specifications of the current blank do not meet the requirements, or there are defects on the surface of the blank, the waste electric push rod 23 will start to push the waste push plate 12 on one side, and then drive the two waste push plates 12 to move synchronously through the suspension frame 13, and bring the blank on the flip panel 7 away from the top of the flip panel 7, so as to realize the automatic removal of blank waste and prevent the waste from flowing into the subsequent process flow. By setting the waste box 29, the unqualified blank will be pushed away from the top of the flip panel 7.The waste is made to fall into the waste bin 29 along the discharge ramp 31 for collection. When the weighing platform 28 senses that the overall weight of the waste bin 29 exceeds a predetermined threshold, the two transmission electric slide rails 24 will drive the two electric slides 25 to carry the waste bin 29 to one end. At this time, the staff can pull the flip handle 30 on the back of the waste bin 29 to drive the waste bin 29 to rotate along the hinge center of the upper rotating plate 27 and the lower fixed plate 26, and dump the waste inside the waste bin 29 to realize automatic collection and semi-automatic transportation of the waste. By setting a dust cover 32, when the waste is pushed down the flip panel 7, a small amount of wood chips remaining on the waste will fall off. The dust cover 32 can prevent a small amount of fallen wood chips from being affected by the ambient airflow. The blanks are blown away from the falling trajectory and directly scattered on the transmission electric slide rail 24, affecting the coordinated driving of the transmission electric slide rail 24 and the electric slide 25. By setting the sorting partition 37, the blanks falling from the bottom of the lower hopper 2 will successively pass through the through hole 3401 at the top and fall between the two sorting partitions 37. Then the sorting motor 35 drives the sorting core column 36 to rotate, so that the two sorting partitions 37 with blanks are gradually turned to the bottom. The subsequent falling blanks will fall again between the next group of two sorting partitions 37, so that many blanks are stuck on the surrounding side of the sorting core column 36 in turn and fall on the upper conveyor belt 4 through the through hole 3401 at the bottom, realizing the automatic sorting and falling of the blanks, greatly reducing the disorder of blank unloading.
